Short answer
If you're switching to a more private period app, the checklist is clear: it should store everything on-device with no automatic cloud sync, require no email or account, run no ads and share nothing with third parties, and let you delete your data easily. A device-level lock (passcode or Face ID) adds another layer. Cyca is built this way — an on-device cycle tracker with no account and no cloud sync, so flow, symptoms, moods and notes stay on your iPhone. It's pay-once, so there's no subscription pushing you toward a cloud account. It's a personal-record tool, not a medical device or contraception.
Try Cyca on a real example first, and check the current App Store listing for exact features and pricing before you decide.

Quick comparison
| Need | What to check | Why it matters |
|---|---|---|
| Pricing model | Check whether useful features require a subscription, a one-time unlock, or neither. | The cheapest app on day one may not be cheapest after a year. |
| Privacy model | Prefer on-device work when the content is sensitive. | Private documents, resumes, study data, and family content deserve careful handling. |
| Export / lock-in | Confirm file formats, sharing, backup, and deletion controls. | A good app should help you finish the task, not trap your work. |
